mod_pubsub: Fix traceback in disco of non-existent node (thanks Martin)
In this case `ret` is a table not containing the node, which makes
pubsub_error_reply() try to get an error template with that `ret` table
as index, which returns a `nil` then passed to table.unpack, which in
turn throws the error.
